Abstract (en)

[origin: EP0938126A1] Electrical inlet body for a tube lamp, characterized in that a functional gradient material of an electrically conductive component and of silicon dioxide as the dielectric component is used, that several combined layers are placed on top of one another cylindrically and incrementally, and in this way are continuously staggered from the electrically conductive component to the silicon dioxide, the volumetric ratio (%) of silicon dioxide in this functional gradient material being designated n1, n2, n3,..., nx (n1 > n2 > n3 >...nx), that furthermore L/D ≥ 2, when the diameter of this cylindrical functional gradient material is labeled D (mm) and the total thickness of the combined layers with a volumetric ratio of silicon dioxide of greater than 80% is labeled L (mm), and that the upholding parts of the electrodes (4) proceeding from the surface on the side of the n1 layer are shrunk as far as the combined layers with a volumetric ratio of silicon dioxide of at least less than or equal to 80%. 2. Electrical inlet body for a tube lamp as claimed in claim 1, wherein d/D is in the range from 0.12 to 0.6, when the diameter of the electrode carrier is labeled d (mm). <IMAGE>
